SPECIFICATION forming part of Letters Patent No. 648,853, dated May 1', 1900.

Application led March 23,1898. Serial No. 674,853. (Model.) v

Tri all '11.71.0711, z'fb my concern:

Be it known that I, JAMES T. OOWLEY, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Pneumatic-Despatch Carriers, of which the" following is a specification.

The object of this invention is to so construct a carrier that it is impossible to insert the carrier into the pneumatic-despatch tube until the cover is closed and locked to the bod. of the carrier and also after the coveris closed and locked to the carrier and the @arrivais inserted in the tube it will be impossible for the. cover to become' unlocked' and open while the carrier is in the tube and in transit.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure l is a front elevation of the carrier with the cover open and showing the fingers projecting which prevent the insertion of the 'carrier when the coverl is open. Fig. 2' is a side elevation with a part of the carrier and cover in section, the section of the cover being taken on the line X X, Fig. 1. Fig. 3 is a detail side view showing the cover partly down and with the operating parts of the cover in a locked position to prevent the turning of the cover to lock it to the body of the carrier. Fig. i is a detail plan view of one of the plates and showing the projecting fingers which prevent the insertion of the carrier into the tube until the cover has been positively locked to the body of the carrier. Fig. 5 is a plan view of aplate forming apart of the locking mechanism of the cover and showing, partly in dotted lines, the projecting ngers. Fig. G is a plan view of the plate of the cover which is hinged to the carrier and also showing, partly in dotted lines, the plate shown in full lines, Fig. Fig. 7 reprcsentsa side view of the bolt, washer, and nut for holding the parts of the cover together.

Likeletters ot reference refer to like parts throughout the several views.

-of the parts are held firmly in position.

The carrier A is preferably made of sheet 5o or ther suitable metal and is provided at one end with a fixed head B, of felt, usually of larger diameter than the diameter of the body of the carrier. The opposite end of the carrier is provided with a movable cover C, which is adapted, as hereinafter described, to be locked to the body of the carrier.

The cover C is provided with an inner plate D, hinged at E to the body of the carrier and provided on the opposite edge with a projection D', and also provided with a central hole D2, through which the bolt vI passes. 0n the rear side of said plateD are two pins D3,which pass-through v.th earcsh 19@ E F' of the plate F, which is also provided wltn c'extt' hole F3, through which the bolt I passes. On the rear side of said plate F are two pins F2, which pass through the opposite .holes G5 in the plate H up into the felt head C' of the cover, and in this manner said plate is locked to turn as one with the felt head C of the cover C. The plates F and H and the felt` head C' form a cap which 'closes the opening into the interior of the carrier A. The pins D3, which, as above stated, pass through the slots F', then extend into the pockets G2 of the fingersG and G'. (See Fig. 4.) Through the hole G6 of the plate I-l and through the collar G4, resting on said plate, the bolt I passes, and around its rear end is located the Washer J and nut K, by which means all The collar G4 prevents the plate F, upon the screwing up of the bolt I, from pressing down on the fingers G G',and thereby prevents the free motion of the said fingers in the operation of the device.

Secured to the back of the plate II is a spring-catch H', which projects around the edge of theplate Il and is bent downwardly, as shown in Figs. 1 and 3, so that when the cover is open the front edge of this catch will engage with theprojection D' of the plate D.

I press down the coverC against the tensionfof the spring-catch II', (see Fig. 3,) so that the catch Il is moved upwardly by contacting with the catch E2, secured to the body of the' carrier, and the ripper end E3 of the catch E2 will pass up through the recess F4 on the plate F andthe projection D will restin the recess E' of the body of the carrier. Asv the catch Il' is moved from its locking position it is cbvious that upon the turning ofthe head C' and connected plates Fand II the catch will pass over the upper edge of the plate F and lock the cover to the body of the carrier.- As the movement continues the fingers G G will be drawn inwardly by, reason of the pinsyD3 of the plate D moving from the extreme opposite ends of the slotsF' toward the outer ends of said slots, and said pins D, located in the pockets G2, will draw the said lingers inwardly. v

It is obvious from the above description that the carrier cannot be introduced into the tube until it is positively locked, because the fingers G G', if the cover is not locked,will project beyond the body of the carrier asuficient distance to. prevent the insertion of the carricr into the tube, andthese fingers cannot be withdrawn until the spring Il is moved upJ Wardly by the closing of the cover C and the head C turned to lock the cover to the body ofthe carrier.

Of course it is clear that after the carrier hasbeen introduced into the tube the cover cannot become unlocked, because the fingers G G would contact with the sides of the tube and prevent the head C lturning to bringv the recess F4 of the plate F opposite the catch E2 on the body of the carrier.

In brief the operation is as l'ollowsz- The plate D being secured to the body of the carrier A and. the plates h and il being secured tothe felt head C and beingloosely mounted on the bolt I, it is obvious that when the catch l-I is opposite the projection D of the plate yD and'upon a slight movement of the cover C said catch Il'vwould contact with said pro*- jection D', and it is obvious that the said head could not be turned until. the catch ll is pushed upwardly and away from'the projection D', in which case the head C is free to revolve and the upper end E:l of the catch E2 is passed through the recess l1 of the plate l", and upon turning the head C' the upper end E3 of the catchflil2 passes over and is held by the plate E to the bodyof the carrier, with the fingers G G' drawn inwardly. Freni the above it is clear that the cover mustbe actually locked to the body of the carrier before the fingers G G" are drawn inwardly.

I do lnot limit myself to the arrangement `and construction shown, as the same maybe cover to the shell of the carrier, means for operating said locking mechanism, means on said carrier coperating with said locking mechanism and arranged. to project beyond the shell of the carrier and thereby prevent the insertion of the carrier into the despatchtube until the coveris locked to the carrier, means arranged to engagewith said locking mechanism and normally hold said locking mechanism and projecting means against movement, and means with which said holding'means engages for releasing said locking mechanism upon the movement o f the cover into locking position whereby said locking mechanism may be operated to lock the cover to `the carrier and said preventing means may he withdrawn'from beyond the shellof the carrier to permit the insertion of the carrier' into the despateh-tube.
